Quad exhaust?

Something or nothing really, just curious.
Having seen a handful on the road now, I couldn't help but notice that only the inboard tips of the 4 appear to be coked up? Which seemed strange, they are not just for show are they?

Not surprised.  R8 tips are mainly costemtic as well as are many others now.

Pet hate of mine TBH.

It is because the bulk of the exhaust gases pass through the inner pair the outer pair open up with a gate valve that is controlled by the ECU.
